proxyllm-mcp

MCP server for ProxyLLM, the OpenAI-compatible LLM gateway. It gives any MCP client (Claude Code, Claude Desktop, Cursor, Cline, Windsurf, OpenClaw) live model catalogs, plan-savings math, routing-key introspection and provisioning, and an account signup flow an agent can complete on its own: email OTP in, sk_ account token out, HTTP 402 with a checkout link until a human activates the membership.

Install

Claude Code:

Terminal

claude mcp add proxyllm -- npx -y proxyllm-mcp

Cursor, Cline, Claude Desktop, or any client that takes a JSON server entry:

config.json

{
  "mcpServers": {
    "proxyllm": {
      "command": "npx",
      "args": ["-y", "proxyllm-mcp"]
    }
  }
}

No configuration is required to start. Two optional environment variables save passing tokens per call:

PROXYLLM_ACCOUNT_TOKEN: an sk_ (read+write) or rk_ (read-only) account token for the management tools.
PROXYLLM_ROUTING_KEY: a pllm_ routing key for key introspection and key-scoped model lists.

Tools

Free, no account needed:

proxyllm_savings_calculator: monthly OpenAI API bill in, subscription tier + flat total + monthly savings out.
proxyllm_list_models: OpenAI-shaped model list from the gateway.
proxyllm_introspect_key: what a routing key can do (lanes, models, budget, whether a Codex subscription backs it).

Account flow (an agent can run this end to end):

proxyllm_signup: emails a 6-digit code to the operator's inbox. No captcha.
proxyllm_verify_signup: exchanges the code for the sk_ account token (returned once).
proxyllm_account: account state; while unpaid it carries the checkout link and a message written to be relayed to the operator. Poll until plan is "pro".

Provisioning (paid accounts):

proxyllm_create_routing_key: mints a pllm_ key, optionally wiring its provider chain (Codex subscription seats, self-hosted Claude Code bridges, metered API keys) in the same call.
proxyllm_list_routing_keys: keys, plus the wireable lane ids with include_lanes.
proxyllm_usage: 30-day usage summary.

Unpaid accounts get 402 payment_required on management tools by design; the body names the price ($129/mo flat), the checkout URL, and the 48-hour removal deadline for never-activated accounts. Error bodies are returned verbatim because they contain the next step.
